You can either issue the SQL command to select MPEG2
transcoding, or you can add the choice to the menu list in the
C++ source file, and rebuild Myth -- then go in and select
MPEG2. I posted detailed instructions to the list a week or two
ago.

Yes, didn't I say that?

Depends on the definition of "worth it". It allows you to
delete commericals, but if you want N bits/second, you're
proably better off just encoding at that rate to start with.

The code to transcode to MPEG2 is there, and it seemed to work
when I tried it, but the option isn't present in the setup
menus.
